RAILROAD SIGNALING APPARATUS.

QPECIFICATION forming part of Letters Patent No. 316,224, dated April 21, 1885.

Application filed February 20, 1885. (No model.)

To all whom it may concern.-

Be it known that I, EMIL BAUMBAOH, of Fordham, in the city, county, and State of New York, have invented a new and useful Improvement in Railroad Signaling Apparatus, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improvement, showing two posts and their attachments. Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation of the same, part being broken away. Fig. 4 is a side elevation of a part of the same enlarged.

The object of this invention is to provide a railroad signaling apparatus by the use of which a train will cause danger-signals to be displayed as it advances and safety-signals to be displayed in its rear.

The invention relates to a railroad signaling apparatus constructed with posts set in the ground and carrying signal-arms connected by crank shafts and rods, with levers pivoted at the side of the track and operated by the wheels of passing engines or cars. With the crank-shaft of the signal-arms of each following post and the connecting-rod of the operating-lever of the preceding posts are connected, by a single-toothed ratchet-wheel, a weighted lever-pawl, and a connecting rope or chain and its guide-pulleys, whereby the signal on a following post will be withdrawn as the signal on a preceding post is displayed, as will be hereinafter fully described, and then claimed.

A represents a railroad-track, along the side of which and at suitable distances apart are set posts B.

At the forward sides of the posts B are the outer ends of levers O, which are pivoted at a little distance from their inner ends to supports D, attached to the ends of the ties of the track A, or to posts set in the ground. The

levers O are placed at right angles with the rails of the track A, and with their inner ends so near the said rails as to be struck by the treads of the wheels of passing engines and pressed downward, raising their outer ends.

To the outer ends of the levers C are pivoted the lower ends of connecting-rods E, the upper ends of which are pivoted to the outer ends of the crank-arms F, attached to the ends of short shafts G. The shafts G- rock in bearings in the slotted upper ends of the posts B. To the shafts G, within the slots of the posts B, are attached signal-arms H, which, when displayed, project horizontally toward the track A, and when withdrawn hang vertically within the said posts.

To the shafts G, and projecting in the opposite directions from the signal-arms H, are attached pairs of arms I, carrying colored glass plates J, the said arms being so formed as to swing down when displayed into horizontal positions upon the opposite sides of the lamps K, secured in casings L, attached to the upper ends of the posts B, and having openings in their sides for the light to shine through. The casings L can be so formed as to cover and conceal the arms I and glass plates J when swung up from the light; or the said arms can be arranged to be swung into openings in the upper parts of the posts B.

To the shafts G are attached single-tooth ratchet-wheels M, the teeth of which when the signals are displayed engage with teeth formed upon the lever-pawls N, pivoted to the posts B, and which hold the signals securely in place when displayed. The leverpawls N are held against the ratchet-wheels M by weights 0, suspended from the rear ends of the said lever-pawls, and which should be of such a gravity as to only slightly overbalance the forward ends of the lever-pawls.

To the forward ends of the lever-pawls N are attached the ends of ropes or chains P, which are passed around pulleys Q, pivoted to supports attached to the posts carrying the lever-pawls around pulleys B, pivoted to supports attached to the next forward posts, and their other ends are attached to the connecting-rods E at the sides of the said forward posts.

\Vith this construction, as the engine reaches each post B it operates the lever G and dis- N, means for throwing the said lever'pawl into engagement with the said ratchet-wheel, and the rope or chain P and its guide-pulleys Q R, 15 substantially as herein shown and described, whereby the signal on a following post will be withdrawn as the signal on a preceding post is displayed, as set forth.
